This section provides in-depth information about the Email API. The API Reference is meant to be HTTP specific and does not include code examples using the SDKs. If you’re new to the API, consider starting with the Get Started guide, or send vs send async.

​
Base URL

The base URL for API requests is https://api.mailchannels.net/tx/v1. All requests are made to this URL, and must use HTTPS.

​
Authentication

All requests to the Email API must contain the X-Api-Key header with your API key as the value. See the Authentication section for more information about API keys and how to manage them.

​
Troubleshooting

For HTTP status codes and error responses, see the Errors section of the API reference.
